PREPARATA E CUPRO.

Preparations of Copper.

.AERUGO PREPARATA. Dub.' Prepared Vetdegrit.

" Let the verdegris be reduced to powder, and the moresubtile parts be separated in the manner directed for the pre-paration of chalk."

By this process the subacetate of copper is obtained in astate of very minute mechanical division, better fitted for in-ternal use, in the cases for which it is sometimes prescribed.(See JEru°o, Part ii.)

CUPRUM AMMONIATUM.Lond. AmmoniatedCopper.*

" Take of sulphate of copper, half an ounce ; subcarbonnteof ammonia, six drachms. Rub them together in a glass mor-tar until the effervescence cease; then wrap up the ammo-niated copper in bibulous paper, and dry it with a gentleheat."

Ammoniaretum Cupri. Edin. Ammoniuret of Copper.

" Take of pure sulphate of copper, two parts; subcarbonateof ammonia, three parts. Rub them thoroughly together in aglass mortar, until all effervescence is finished, and they unitein a violet-coloured mass, which wrap up in bibulous paper,and dry, first on a chalk stone, and afterwai'ds with a gentleheat. Let it be preserved in a well stopped glass phial."

Cuprum ammoniatum. Dub. Ammoniated Copper.

" Take of sulphate of copper, an ounce; carbonate of am-monia, an ounce and a half. Rub them in an earthenwaremortar, until all effervescence having ceased, they unite intoa mass, which is to be dried, wrapped up in bibulous paper,and preserved in a phial closed with a glass stopper."

The product of these processes is either a triple salt, a sub-sulphate of oxide of copper and ammonia, or a mixture onlyof subsulphate of copper, and subsulphate of ammonia 3 ;but the former is the more probable stale of the compound,from the difference of capacity which it has for water being =sogreat as to render the resulting mass extremely moist. Duringthe trituration, the sulphate of copper is partially decomposed,and part of its acid yielded up to the ammonia, which is ccn-
